Ontario Hst Tax Calculator

Reviewed by Calculator Editorial Team

Ontario's Harmonized Sales Tax (HST) is a consumption tax applied to most goods and services sold in the province. This calculator helps you determine how much HST you'll pay on your purchases in Ontario.

What is Ontario HST?

Harmonized Sales Tax (HST) is a single sales tax that combines the provincial sales tax and the federal Goods and Services Tax (GST). In Ontario, HST replaced the old provincial sales tax system in 2010.

The HST applies to most goods and services sold in Ontario, with some exceptions. The tax is collected by retailers and remitted to the government, with the proceeds used for provincial programs and services.

HST is different from the federal GST in other provinces. In Ontario, the HST combines both taxes into one rate.

How is HST calculated in Ontario?

The HST is calculated as a percentage of the price of the goods or services being purchased. The formula is:

HST Amount = (Price × HST Rate) / 100

Total Price = Price + HST Amount

For example, if you buy a product priced at $100 with an HST rate of 13%, the calculation would be:

HST Amount = ($100 × 13) / 100 = $13

Total Price = $100 + $13 = $113

The HST rate varies depending on the type of product being purchased. Some products are tax-exempt or have reduced rates.
